Patent CA-2288559-A1 (CA)
Inventor: CHER EDMUND K
IPC: H04Q11/04
Filed: 1999-11-04
Abstract: A system and method are disclosed for processing digital signals in a telecommunications system that allow hit-less switching between a first digital signal in which a first payload, a first payload indicator marker and a first overhead are transported on a first channel, and a second digital signal in which a second payload identical to the first payload, a second payload indicator marker and a second overhead are transported on a second channel. The present invention includes first and second pointer followers, first and second elastic buffers with control circuits, a monitor circuit, a multiplexer, and a pointer generator. The first and second elastic buffer control circuits each further comprise a write counter, a read counter, a phase detector, and a leak-out mechanism for reinitializing the system after a protection switch.      The present invention hit-lessly selects between the first and second digital signals without having to frame align the signals.
Patent CA-2291405-A1 (CA)
Inventor: MACDONALD I ROBERT
IPC: G02F1/065
Filed: 1999-12-02
Abstract: This invention discloses an optical waveguide having a hybrid core useful in the fabrication of a host of active and passive optical devices. The core is primarily inorganic glass having a lesser portion of polymer grafted therein. Preferably, the polymer has a substantially different thermo-optic coefficient. By appropriately selecting a polymer with a suitable thermo-optic coefficient a temperature stable waveguide can be fabricated. Active devices having a smaller section of polymer can be realized with heaters for varying the temperature and hence the refractive index of the polymer section.

Title: Cryptographic token and security system
Inventor: LARAYA JOSE LUIS R
IPC: G06F1/00
Filed: 1999-12-13
Abstract: There is disclosed a secure internet telecommunications system for transmitting, encrypting, receiving, and decrypting data across the Internet. The security system includes an internet security module which is positioned between a first computer and the internet. The internet security module transmits data from the computer through a modem onto the internet. The security module has a cryptographic logic device that encrypts and decrypts data transmitted from the first computer in accordance with known standard encrypting and decrypting protocols.      The security module is actuated by the insertion of cryptographic token bearing a user's cryptographic key information. This token is inserted into the security module and must be enabled to make available cryptographic key information to the security module for use in encrypting and decrypting data. The cryptographic token is preferably a card having a tamper proof casing and a contact sensitive liquid crystal display for displaying messages to a user. The token captures and stores a template associated with a user's ideogram signature information which is compared with subsequent inputs of this ideogram signature information from the user to enable the cryptographic token to function with the security module. The cryptographic token has an independent power source permitting the token to be enabled preferably off line from the internet security module. The present invention has advantage in that the cryptographic key information is stored on a token device that must be enabled by a user and temporarily connected with the internet security module to permit the use of the user's cryptographic keys.

Title: Methods and apparatus for adjusting power in an optical signal, for providing a seamless optical ring and for providing a bidirectional equalized amplifier
Inventor: ADOLPH STEPHEN KIERAN
IPC: H04B10/17
Filed: 2000-03-20
Abstract: A method and apparatus for adjusting power in an optical signal are disclosed and a bidirectional equalized amplifier for providing bidirectional equalization, employing the apparatus and method is disclosed. Use of the method and apparatus to form a seamless ring in an optical network is also disclosed. The method of adjusting power involves splitting an input composite signal into respective drop signals in separate wavelength bands with a splitter. An attenuator attenuates the drop signals to produce attenuated drop signals. A combiner combines the attenuated drop signals to produce a first output composite signal in which the power is equalized. The bidirectional equalized amplifier involves a first apparatus as described above for splitting, attenuating and then combining signals in respective wavelength bands of an input composite optical signal, to produce a first output composite signal. An amplifier amplifies the first output composite signal to produce an amplified first output composite signal which is passed through a reverse path in a second apparatus of the type described above to a second input port of the second apparatus, for transmission on an optical medium, while selectively splitting, attenuating and then combining signals in respective wavelength bands of a second input composite optical signal, received at the second input port of the second apparatus to produce a second output composite signal. The second output composite signal is then amplified to produce an amplified second output composite signal which is then passed through a reverse path in the first apparatus to the first input port of the first apparatus for transmission on an optical medium.

IPC: C10F5/00
Filed: 1998-08-25
Abstract: A method and an apparatus for upgrading a solid material is disclosed. The method comprises heating the solid material to an elevated temperature to remove water and thereafter cooling the upgraded solid material. The method includes providing a plurality of vessels containing packed beds of the solid material and one as more than one heat exchange circuit for heating and cooling the solid material in the packed beds in the vessels by heat exchange with a heat transfer fluid. The method is controlled so that the solid material in a first group of the vessels is at one or more stages of a heating cycle and the solid material in a second group of vessels is at one or more stages of a cooling cycle. Specifically, the method is controlled by selectively connecting the one or more than one heat exchange circuit to the vessels so that the heat transfer fluid recovers heat from the solid material undergoing the cooling cycle in at least one of the vessels in the first group and transfers the recovered heat to the solid material undergoing the heating cycle in at least one of the vessels in the second group.

Title: Method for producing multi-layered preforms
Inventor: FERNANDEZ LUIS
IPC: B29C45/16
Filed: 1998-11-04
Abstract: The inventive method for producing multilayered preforms makes it possible to create extremely thin layers, especially a thin surface layer and/or a thin barrier layer. These thin layers are at the most 35 % and 5 % respectively of the overall volume. They are produced using a multi-component injection moulding form tool which is operated in such a way that the plastic component provided for creating the thin layers is conveyed through the innermost jet chamber. Said plastic component has a slightly higher temperature and is therefore slightly viscous. Preforms produced in this way are characterised by a surface layer representing less than 35 vol. % or a barrier layer representing approx. 5 vol. %.
